IMPROVEMENT IN RAILROAD TIES.

Specification forming part of Letters Patent No. 139,518, dated June 3, 1873 lapplication filed April 12, 1873.

To all whom it may concern:

Be it known that we. WATSON PEGK and HENRY U. RIGHMAN, of Lombard, and county of Du Page, and State ot' Illinois, have invented a new and useful Improvement in Compound Railroad Ties, of which the following is a specification The object of the present invention is to provide Inore durable ties to be used in the construction of railroads, and which can be repaired without disturbing the bed ot' the road; and its nature consists in employing' for each' tie two metal chairs which are recessed A out on their under sides toprevent a lateral lnovement, and are provided on their top I sides wlth grooves to receive a metal connecting-plate ot' novel construction, which is provided with `upward-projecting tlanges, fitting into the grooves in the chairs, and receiving short block-ties to support the rails, and provided with downward-projecting ribs to support the middle ot' the plate, as the whole is hereinafter described and shown.

In the drawing, Figure 1 is a perspective representation of our ixnprovernentin railroad ties Fig. 2, a broken perspective viewot' the connecting-plates; Fig. 3, a perspective view of one of the blocks for supporting the rails; Fig. 4 is a section through one of the chairs, showing the recess and how the parts are connected.

A A represent the metal chairs of one tie which are recessed out on their under sides as shown, so as to form such seats as will prevent the chairs from moving laterally when they are thoroughly beddedin the roadway, and which are provided with grooves or dovetailed channels on their upper sides to receive the a'nged ends G of the connectingplate E, said dan ges conforming in inclination to the inclined sides of the grooves in the tops of the chairs, being of such size as to fit therein, as shown in Figs. 1 and 4. The centrai portion of the connecting-plate E is provided with downwardprojecting ribs F on both sides, to give it suitable strength, that it may be light and strong. It' the said plate be thicker the ribs may be dispensed with, but when ribs are used theyr should extend into the chairs A, grooves beirg made for that purpose. D represents short blocks, which are of suitable size to support the ordinary rails of a road, and to receive the spikes which keeps the rails in place, and which are driven in between the iianges G and held there by bolts X X. The connectingplate E should be made of malleable or wrought-iron, but the chairs can be of cast-iron. III practice the blocks D can be of wood, and about six inches thick, eight inches wide, and eighteen :inches long.-

We claim and desire to secure by Letters Patent- The combination of the chairs A, constructed with o r without recesses, with the connecting-plate E and blocks D, substantially and for the purpose described.
